Please answer the following questions......

Dear Student, Some metal oxides show both acidic and basic behaviour. The metal oxides which react with both acids and bases to produce salt and water are known as Amphoteric Oxides.  As aluminium oxide reacts with both acids and bases and produces salts and water, therefore aluminium oxide is considered as Amphoteric Oxide. Equations- (1)Al2O3 + 6HCl ==> 2AlCl3 + 3H2O (2)Al2O3 + 2NaOH ==> 2NaAlO​2 + H2O. B) Iron is more reactive metal than copper and thus displaces copper from its sulphate solution and forms iron sulphate solution, leading to fading of blue colour of copper sulphate and copper occurs as the red deposit on the iron strip.  Fe(s) + CuSO4(aq) → FeSO4(aq) + Cu(s) . Kindly ask remaining question in next thread. Regards
